Abstract
The present lift lock is employed on a gate that is swingable and liftable on a first axis. In a first position the lift lock is on the first axis and in a blocking position that prevents the gate from being lifted relative to a barrier having the gate. The lift lock is slideable away from the first position on the axis to a second position away from the axis where the lift lock is in an unblocking position, thereby permitting the gate to be lifted on the axis. The lift lock snaps into and out of the second position.
